Do I do it?? Nope.....I abuse my tranny enough without powershifting. I'm still waiting for the day I finally destroy it (sadly, I have a feeling my ceramic clutch is gonna go first ). Of course, I'm the same guy who refuses to ice his intake; guess I'm just not desperate enough to shave a couple of tenths.

But hell, if you are rebuilding it, why not?? AND add some juice while you are at it. AND launch the **** out of the car.

Well, that sorta sums it up. I am planning on a tranny rebuild as well as some other mods over the winter and I would like to see 10's out of the current combo. My best to date was 11.08, without powershifting. It's a bit down on hp, otherwise it'd be there already. So I've been trying to think of how to shave off just a tenth, even at the risk of breaking something. A 1-2 powershift will likely break 'em loose, so I think I'll try powershifting 2-3 and 3-4. From all I can tell it should be good for a tenth, at least.

I also just installed slight larger nitrous jets but haven't had the chance to run them yet as the track was rained out on Sunday

Thanks for the opinions!
